Differences between Examples XCode Default Schemes ?

Hi there,
I guess it isn’t really a specific question to XCode…

Each examples have at least 2 schemes, whatever the kind of examples (I mean iOS targets, OSX targets too)

  • for the OSX’ ones, there are always Openframeworks &
  • for iOS’ ones, there are always iPhone+OF Static Library &

Could someone explain me the differences between all those schemes ?
